(Format 23,5x16 cm.) Armed with a large drill-bit, GX Jupitter-Larsen hurls himself from 3,000 meters. During descent, he drills a hole in the sky as literal as only he could -- ∆G all along the "polywave." And thus the title of this handsomely packaged, shoddily reproduced grimoire from John Wiese's Helicopter imprint.
